"Here's for sale The Mega Rare & Highly Sought After ULT-SOUND DS-4 Custom By Toyo Gakki made in Japan in the Early 70s... The Ult Sound DS-4 is an amazing Analog Drum Machine composed of 4 Oscillators which can be triggered from the Voltage Control Inputs either all Oscillators at once or each Oscillator individually, each Oscillator section is capable of producing a wide range of different sounds from Bass Drums, Snares, Cymbals, Etc, as well as all kinds of space sounds & other very complex sounds which made this Analog Drum Machine famous for those particular sounds at the time.
There were two models of these units made, the "BLACK" faced model which was the most common and the "CUSTOM" Model which is the hardest to find usually sell for over $ 3,100 but I am only selling mine for $ 2,650 shipping included because Christmas is coming and wanna buy some new stuff in my studio.
Many artists and bands like The Yellow Magic Orchestra used the Ult-Sound DS-4 in their live performances and recordings in the late 70's and early 80's..."
